PLOW.

Specification of Letters Patent.

Patented July 30, 1912'.

Application filed October 4, 1911. Serial No. 652,722.

citizen of the United States, residing at Macon, in the county of Bibband State of Geor ia have invented certain new and use.

ful Improvements in Flows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to plows and while especially adapted for use inconnection with double mold-board or middle-burster plows is not limitedto such plow structure.

An object of the present invention is to provide improved means forreadily attaching and detaching the plow bottom to and from the beamwith which it is operated.

A further object of the invention is to provide in the frog of a plowimproved means for connection with the beam and with a depth runner.

A further object of the invention is to provide a beam composed ofdouble spaced bars with a spacing lug or block at their lower endshaving a nose adapted to fit in a notch in the frog and to embrace a lugcast integral with the frog, said lug also serving to position the depthrunner.

With these and other objects in view the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter more fully described and claimed.

In the drawings :Figure 1 is a perspective view of a double mold-boardplow embodying the present invention, showing one of the mold-boardsbroken away and removed. Fig. 2 is a view in vertical sectionsubstantially through the center of the plow bottom. Fig. 3 is aperspective view of the lower extremity of the double beam showing thespacing lugand engaging nose. Fig. 4: is an inverted plan view of thefrog and beam attached thereto, with the attaching lug broken away.

Like characters of reference indicate corresponding parts throughout theseveral views.

The frog 10 shown in the present invention is provided with a lug 11upon its under side proportioned to be inserted between the spaced bars12 and 13 of the double beam, illustrated at Fig. 1, and with a spacerblock 14 rigidly secured between the extremities of such bars 12- and 13of such thickness as to properly space the bars to embrace the lug 11and provided with a nose 15.

The frog is provided with two notches, as shown particularly at Fig. 2,one of which receives the nose 15 of the spacer block and the otherreceives the extremity 16 of the depth runner 17, the depth runner beingfurther secured to the extremity of the lug 11 as by bolts 18. So as notto throw the depth runner 17 off center, the lug 11 is preferably thrownoif center, as shown particularly at Fig. 4, and a rib 19 is providedwhich properly spaces the beam bars 12 and 13 relative to such lug, saidbeam being further secured to the frog by means of a bolt 20 whichpasses between the bars 12 and 13 and through the upper shank of thefrog and is provided with a nut 21 and means for ready manipulation ofsuch nut. To place the plow body in position upon the beam the depthrunner 17 is removed, the lug 11 inserted between the bars 12 and 13,the nose 15 brought into position in the notch of the frog with theopposite side of the spacer block 14: bearing against the lug 11 and thebolt 20 put in position with the nut 21 placed thereon. The depth runneris now returned to its position by inserting the extremity 16 in thenotch of the'frog and inserting the bolt 18. It will thus be apparentthat the beam composed of the bars 12 and 18 may be readily employed forconnection with a great variety of soil tilling implements provided withsimilar lugs 11 and ribs 19 which may be secured interchangeably to thelower extremity thereof and that as in the present case they may bereadily changed by the ready re moval and replacing of the said tillinginstruments.

I claim 1. In a plow, a frog, a beam composed of spaced bars, a lugcarried by the frog proportioned to be inserted and embraced between thebars of the beam, a spacer block carried by the beam and provided with anose proportioned to be inserted in a notch in the frog, and a boltadapted to be inserted through the frog and between the beam bars.

2. In a plow, a frog, a lug extending downwardly from the .under side ofthe frog, a beam composed of spaced bars proportionedto embrace the lug,a spacer block carried rigidly by the extremities of the bars 'Gopies ofthis patent may be obtained for and having a block provided with a noseadapted to fill the space between the lug and shoulder and to engage thenotch.

In testimony whereof I afix my signature in presence of tWo Witnesses.
